This video shows how children are learning maths with multisensory resources. In my practicum I used the material shown in the video (the plastic colored patterns with with holes) and they used this material almost everyday in different ways. One of the activities I was in charge to do with them consisted on me asking them how would they represent a number, and they had to represent it with the patterns. For example if I said "Number 6", they would try to form the number 6 adding for example a pattern with 2 holes, with another one with 4 holes. This way they were adding without realising they were doing mathematical calculations and they were seeing additions as something very visual.
2. Material manipulativo de Montessori (Montessori manipulative material).

This video shows how to use a manipulative resource about descomposing numbers through little sticks and balls. During my practicum, I also had the chance to see how they were using these kind of materials and I could really see results. They were using these material for a while during the first term and later on, when they started to do additions on paper their understanding and speed to solve the additions was very optimum.
3. Tabla de multiplicar Waldorf (Waldorf multiplication table).

In contrast, I had never seen this material before, until I watched this video, and I found it very interesting. The video proposes a method to explain and understand better the multiplication tables with a wooden board, tacks and a thread. It makes children understand multiplication tables and see them in a much more visual way. Each table corresponds to a different geometric figure and thread. It is a material that, of course with the help of the teacher, can be created in class with students of the second cycle at least.
4. Tutorial Manipulativos Medida Tiempo (Tutorial to create manipulative material to work with Time Units)
https://www.youtube.com/watch?v=iWATGSQKUTM
It proposes a manipulative material to work the time units. The teacher in the video has created cards with units of less than one day (hours, minutes and seconds) and with larger units like (week, month year, century and millennium). It gives examples of activities for this material such as: decomposition of years, different expressions of time and how to carry out problem solving through these cards.
